useFormContext

useFormContext: Function

This custom hook allows you to access the form context. useFormContext is intended to be used in deeply nested structures, where it would become inconvenient to pass the context as a prop.

You need to wrap your form with the FormProvider component for useFormContext to work properly.

Props

Name	Type	Description
`...props`	`Object`	Accept all `useForm` methods.

import React from "react";
import { useForm, FormProvider, useFormContext } from "react-hook-form";

export default function App() {
  const methods = useForm();
  const onSubmit = data => console.log(data);

  return (
    <FormProvider {...methods} > // pass all methods into the context
      <form onSubmit={methods.handleSubmit(onSubmit)}>
        <NestedInput />
        <input type="submit" />
      </form>
    </FormProvider>
  );
}

function NestedInput() {
  const { register } = useFormContext(); // retrieve all hook methods
  return <input {...register("test")} />;
}
